(Cl. E- 1) 1 Claim.

yThis. invention relates to passenger railroad trains and moreparticularly to the arrangement of equipment for personal accommodationsof the passengers and the manner of supplying fresh water to vsuchequipment.

It is the usual practice to provide each passenger car individually withthe equipment for personal accommodations of the passengers therein.`Such equipment usually includes toilet facilities, drinking water `andair conditioning apparatus. Usuallythe drinking water is suppliedseparately to an iced cooler while the other equipment is supplied withWater from a storage tank mounted on the car. The equipment is locatedpartly in the roof, under thecar and in room space Vwhere it isgenerally inaccessible and difficult to install and service.

An object of this invention is to improve railroad train structure byproviding service cars containing al1 of the equipment andv spacerequired for personal accommodations of the pas* sengers.

Another object of this invention is to provide a railroad passengertrain in which all of the equipment required for personal accommodationsof the passengers is supplied with fresh water by a feed line connectedwith a reservoir located in 'the locomotive;

A `further object of the invention is to provide a railroad passengertrain with service cars located' between vpassenger cars and containingequipment including apparatus for conditioning the airV in adjacentpassenger cars.

These and other objects of the invention will lbe apparent` to. thoseskilled in the artfrom a study of the following description andaccompanying drawings, in which:

Figure 1 is a side elevational view of a portion of a passenger railroadtrain incorporating the invention.

Figure 2 is a horizontal sectional view of the train.

The railroad train illustrated by the drawings is comprised of alocomotive L, a baggage car B, passenger cars P and service cars S. Thebaggage car is located directly behind the locomotive and is connectedthereto by suitable coupling means such as that forming the subjectmatter of ap,- plication Serial No. 41,485, filed July 30, 194'8, byRobert Walsh Vand JaclcD. Kennedy, now Patent No. 2,601,928. TheAservice fears` are preferably located-between passenger cars and inunits con.- taining one service car with two passenger cars at eachendthereof. The cars can be of the character andcoupled together asshow-n in Patent No. 2,462,666, issued February 22, 1949,` to Alej androGoicoechea Omar.

The only equipment in the passenger carsk consists of chairs 1.0, orother furniture upon which passengers may recline. Passengers enter andleave thetrain through` side doors I I inthe service cars and centeraisles l2. provide passageways through the passenger `and service cars.All equipment for the personal accommodations `of the* passengers is inthe service cars. Such. per.- sonal equipment for the passengersincludes a refrigerated drinking station I4, .hoppers I5, wash-basinst6, sink Il, .baggage compartment I8 and water tempering apparatus I 9for conditioning air. rPhe washbasins and hoppers are arranged in toiletrooms 20 at one side and near the endsof. the service-cars, the sink isin akitchen opposite one of the toilets' and` the baggage room isopposite the other toilet room. T-he drinking station is between one ofthe car side doors and a toiletrroom and the water tempering apparatusis opposite the drinking station.

Equipment in the service cars-.S isY supplied with fresh water by asystem in which a main supply line 21 passes through the trainV fromVreservoir meansZZ. n1 'the locomotive; to the rearmost serv-- ice car.`The, reservoir means in the locomotive, the air pressure system and theAcontrol of the water are the subjectmatter of applicationiserial No.113,727", led September 2f, 1949 byA Robert Walsh. The reservoir means22 preferably' comprises. two tanks` suitably mounted in therearend ofthelocomotive;

Valve devices are associatedwith each tank Vfor controlling the Watersupply and theair pressure. Each water valve device includes a housing4i! having an outletend that screwson an inlet pipe llt `leading to the`interior of the adjacent tank. Within eachhousing 40 is a spring closedvalveAZ. ,and a manually operated wobble valve 43 is arranged at theoutside of the casing. Lever 44 is attached to the casing on pin 45,valve 43 is mounted on pin 46 carried by the lever and spring 41normally acts on the lever to close the wobble valve. When valve 43 ismanually opened, a water supply hose, from a source exterior of thelocomotive, can be inserted into the inlet end of the housing and willhold valve 42 open during the filling operation. Water can be suppliedto either inlet housing to ll both tanks as they are connected by anequalizer pipe 43. The tanks have a pressure blow-off valve 49 so thatair pressure in the tanks is maintained below a selected maximum. Wateroutlet pipes 59 extend through the top of the tanks and are openadjacent the bottom of the tanks. Pipes 59 join with an outlet pipehaving a manually controlled valve 52 at its end to which a flexiblepipe 53 is attached. Pipe 53 extends outside of the rear wall of thelocomotive and has a coupling 54 at its end for attachment to train line2l.

Air under pressure can enter the tanks from valve housings 55 attachedone to each of the water inlet housings 49. Inlet pipe 55 is connectedwith the inlet 51 of one of the air inlet valve housings and pipe 59connects with an outlet 59 of such air valve housing and is connectedwith the inlet of the other air inlet valve housing. Pipe 6l! and branchpipe 6l connect the second air valve housing with the upper portion oftanks 22. The air valve housings each have a vent pipe 62 attached tooutlets 63. Two-Way valves 84 in such housings 55 are rotatable byhandles 65 to connect the air inlet pipe 59 with pipe 58 and pipe 58with pipes B0 and 8i for a1- lowing air flow to the tanks and this isthe condition existing except when water is to be admitted to the tanks.When the tanks are to be supplied with water, the valves are turned tocut off flow through pipes 58, 99, and 6l and will connect supply pipes56, 58 and 69 with vents 62 to thereby allow air to escape from thetanks and to cut off the source of air supply. Gauges 65' indicate theheight of water in the tanks and air pressure on the water in the tanksis maintained at approximately 100 lbs. pressure. When the air system isopen to the tanks, valve handles B5 will overlie and lock levers 44 tomaintain valves 43 closed. But, when handles 65 are moved to release airpressure from the tanks, then their position is such that valves 43 canbe opened. A pressure eoualizer valve 65 is connected with supply pipe56 to hold the air in the tanks at the desired maximum pressure and thevalve 96 is connected by pipe 61 to compressor 68 mounted in the rearportion of the locomotive in advance of the tanks and driven by electricmotor 69.

The locomotive is powered by two main enginegenerator units 'i9 and-contains auxiliary enginegenerator units 'Il for furnishing theelectricity required for various apparatus associated with thelocomotive and train. The main units are connected with a control board12 by wiring 13 and the auxiliary units are connected with the controlboard by wiring 14. Wiring connects the control board with batteries 16and wiring 'E1 connects the control board with motor 69 for operatingcompressor 68 with which the compressed air line 81 is connected.

The main water supply line extending through vthe train consists ofpiping 80 suitably secured in each car and projecting past the ends ofthe cars. These projecting ends of the piping preferably have aselfclosing valve therein (not shown) of conventional type and areformed to receive quick-detachable couplings 54 on the ends of flexiblehose sections 53, see Figs. 1 and 5. The piping in the baggage andpassenger cars is shown as a straight length, while in the service carsthe piping is composed of a straight intermediate section 81 offsetlaterally from the end sections 92 and joined by transversely extendingsections 83 and 94.

The piping in each service car is connected with the apparatus in suchcar by valved feed lines as shown in Fig. 4. Feed lines 85 are connecteddirectly with the transverse piping sections 83 and 84, one of thesefeed lines and one end of the other feed line having a valved outlet endoverlying washbasins I9 while the other end of the latter feed lineterminates in a valved outlet over the sink. Feed lines 86 are connecteddirectly with piping section 8| and have valved ends connected withhopper i5 and washbasin I6. Feed line 81 is connected with pipingsection 8| and the drinking station I4, such line terminating in afaucet 89 and coiling through conventional refrigerating apparatus inthe station. Feed line 89 leads from piping section 8| to the temperuniti9 from each end of which water lines 90 and 9i extend to form a circuitthrough the adjacent passenger cars. Valve 93 controls the flow of waterthrough feed line 89 to the temperature conditioning apparatus for watercontrolling the air conditioning in the cars.

The service cars are also provided with a water tank 94 located in thebaggage compartment i8 heated by an electric coil 95 or other suitablemeans. Water iiows to the tank from the main feed line section 83through pipe 96 and piping leads from the heating tank to the sink andWashbasins. Such hot water piping comprises sections 95, 9?, 98 and 99,the section 98 and one end of section 99 terminating above thewashbasins and the other end of section 99 terminating above the sink.Spigots IDI are fixed on the ends of the washbasin lines 85, 98 and 99and spigots |02 are fixed to the ends of lines 85 and 99 above the sink.

It will be observed that all personal equipment and entrance doors tothe train are in the service cars thereby leaving spacious accommodationfor occupants of the passenger cars. It is also evident that the waterreservoir in the locomotive supplies all of the water to the equipmentin the service cars thereby conserving some of the space formerlyrequired in the passenger cars.

The invention may be modified in various respects as will occur to thoseskilled in the art and the exclusive use of all modifications as comewithin the scope of the appended claim is contemplated.

What is claimed is:
